Identify features of the economic business cycle. 1  Business cycles are identified as having four distinct phases: expansion, peak, contraction, and trough.  Business cycle fluctuations occur around a long-term growth trend and are usually measured by considering the growth rate of real gross domestic product.
The voltage induced in the coils are proportional to the rate of turn of the vessel or vehicle such as a towboat utilizing the rate of turn indicator 10. The bridge rectifiers 63 and 65 rectify the coil voltage to a DC voltage to operate the rate of turn meter.. Field of the Invention. The present invention relates to a navigational aid or nautical instrument, and more particularly, pertains to a rate of turn indicator for indicating the rate of turn from a course of travel for a vessel or other like vehicle.
The result is that at the working vacuum level of 23 mbar, as in the hypothetical example above, Pump X has a pumping speed of only about 0.9 m3/hr. The PC 3001 VARIOpro, with a specified flow rate that is one-third less than Pump X, pumps 60% faster at a working vacuum level of 23 mbar. The PC 3004 VARIO pump, with a flow rate specification 50% higher than Pump X, has a pumping speed at the working vacuum level that is three times that of Pump X.
